The baseline run showed it to be running really rich all over (see chart), the jetting was pilot 38, main 112 front, 110 rear, screw 2.5 turns.
The dyno tech dropped the jetting to 102 in the front, 100 in the rear, left the pilot jets and screws alone but removed the fat shim from under the needles.
The results were good, the chart showed it made nearly 100 HP (up form 87) and probably would have cracked 100 if he had run it 500 rpm more.
You can see the two runs, the first run looks very linear 'cos the tech reckoned he hadn't got the tach sensor in the right place. The second run is not that smooth
as the tyre was giving out (it was just about bald).
This has translated to a lot more throttle response and more go all through the rev range - it pulls cleanly all the way to the red.
I am going to get a pipe next, I have a local source to make me a very nice (or so they claim) 4-2-1 joint pipe to go from the stock headers to some flavour of slip on - I could
get a few of these made if anyone is interested - I know the availability of aftermarket pipes is rather limited.
